Problem Statement
What is the role of the dispatcher in process scheduling?
Explanation
The dispatcher is the component of the operating system that gives control of the CPU to the process selected by the scheduler. It performs the context switch, switching from kernel mode to user mode, and jumps to the correct place in the user program to restart it. Its responsibilities include switching context, jumping to user code, and switching to user mode. The time the dispatcher takes (dispatch latency) affects how quickly a ready process begins execution, and therefore influences system responsiveness.
